SPECIFICATION forming part of Letters Patent N 0, 721,22?, datedFebruary 24, 1903.

Application ieanprn 26, 1902.

To all whom it may concern:

Be it known that I, PHILIP H. T. PAULI- NETTI, a citizen of `the 'UnitedStates, and a resident of Philadelphia, in the county-.of Philadelphiaand State of Pennsylvania, have invented a new and useful HeatingApparatus for Beds or Couches, of which the following is aspecification.

This invention is a heating appliance to be used in connection with bedsor couches for the purpose of applying heatv to the entire body or anyparticular portion thereof, the object of thei'nvention being to providean eX- ceedingly cheap and simple appliance which can be used inconnection with any of the beds or couches now in com mon use and whichwill take the place of the ordinary mattress and springs. y

With this object in view the invention consists, essentially, of ahollow body, preferablyformed of air-tight fabric divided into two ormore compartments, each compartment-being provided with springs and alsowith means for supplying hot air thereto.

The invention consists also in certain details of construction andnovelties of combination all of which will be fully describedhereinafter and pointed out in the claim.

In 'the drawings forming part of this specification, Figure 1 is aperspective view illustrating the practical application of myinvention.Fie. 2 is a longitudinal sectional view, the heat-collecting funnelbeing also shown in section. Fig. 3 is a sectional view on the line 3 3ofFig. 2. Fig. 4 is a sectional perspective view showing'a cushionformed of a single section. Fig. 5 is a detail view illustrating thecut-off clamp, and Fig. 6 is a detail perspective of the pillow.

In carrying out my invention-I employ a hollow body A, composed of the'bottom A', top A2, and the ends and sides A3, all of said parts beingpreferablyconstructe'd of air-tight fabric, and such parts may be of anysize and shape desied. The bottom A may be of stonter and stiffermaterial 'than the sides and top, although this is not absolutelyessential. Angular supporting-arms are connected to the bottom of thebody A, extend upwardly along the sides thereof, and project laterallyat their upper ends for the purpose of engaging the side rails C of thebed, thereby sup- Serial No. 104,899. (No model.)

porting the hollow body A within the bedframes and virtuallyconstituting the mattress for the said bed. A series of leaf, spiral, 0rother form of springs D are arranged within the hollow body A, saidsprings being preferably connected to the bottom. These springs hold.the top elevated and provide an elastic resting-surface for the patient.The hollow body A may be of such size as. to entirely cover the bed, asshown in Fig. 1, or it may be a smaller section, as shown in Fig. 4. Theconstruction shown in Figs. l and 2 is intended to apply the heat to theentire body, whereas the construction shown in Fig. 4 is intended toapply heat only to a certain portion of the body.v I prefer, however, todivide the hollow body A (shown in Figs. 1 and 2) into a series oftransverse compartments by means of the transverse partitionsE,connected tolthe top, bottom, and sides of 'the hollow body, and eachcompartment has a pipe F leading thereto, said pipes uniting in acentral pipe G, which is connected tol the heat-collecting funnel H,adapted to be arranged over a lamp I or any other source of heat. Eachpipe F is provided with aclam p K,coinprising the members K', hinged atK2 and having a screw-bolt K3 passing through theirfree ends and bymeans of which the membersL' can be contracted or expanded to close oropen the pipe F. Byrneans of a device constructed as herein shown anddescribed I am4 enabledto supply heat directly to 'theV entire body orany particular portion of the body,as it will be understood that byclosing the cut-0H clamps the air can be cut off from any particularcompartment. Furthermore, by means of the cushions, such as shown inFig. 4, heat canbe applied to any particular part of the bodyirrespective of the construction of the `mattress of said bed.

, Ii' desired, a hollow pillow I may be removably arranged upon thebodyAand heat conveyed into the pillow by means of a pipe F', which isconnected to the central pipe G of the collecting-funnel, or, ifdesired, a separate funnel may be employed to collect the heat from anysuitable source. The pipe F is also provided with a Valve, as shown, andin practice I also prefer to make the pillowcasing of stout fabric andhold the same open by means of a-spiral spring M that extends ICO /I 15divided into a series of compartments, each compartment'havng a seriesof springs arranged therein, the angular supporting-arms connected tosaid hollow body, a heat-collecting funnel, a main pipe connected tosaid heat-collecting funnel, branch pipes extending from said main pipeand connected with the separate compartments of the hollow body, and thecut-o clamps arranged upon said branch pipes, substantially as shown anddescribed.
